The role of serum eosinophil cationic protein levels in allergic rhinitis is controversial. It is also unclear whether with immunotherapy it is possible to reduce these serum levels in allergic diseases. We studied serum eosinophil cationic protein levels in patients with cedar-induced allergic rhinitis and compared them with non-atopic controls. The second aim of this study was to elucidate whether immunotherapy is capable of decreasing the seasonal elevation in serum eosinophil cationic protein levels in seasonal allergic rhinitis. The serum eosinophil cationic protein levels of the untreated patient group were significantly higher than those of the non-atopic controls. The levels in patients who received immunotherapy for 2 yr were also significantly higher than those of the non-atopic controls. However, the levels were not different between the patients undergoing immunotherapy for over 3 yr and the non-atopic controls. The serum levels of the 31 patients treated with immunotherapy correlated with the duration of immunotherapy. In conclusion, the serum eosinophil cationic protein levels are higher in untreated patients with seasonal allergic rhinitis and this seasonal activation in circulating eosinophils decreases gradually during immunotherapy, but this inhibitory effect becomes apparent only after a number of years of immunotherapy. This prevention of seasonal eosinophil activation is one of the mechanisms responsible for the clinical effect of immunotherapy. 相似文献

A 4 month old female infant with atypical asymmetrical massive gray matter heterotopia diagnosed as West syndrome is described. Her seizure initially appeared as afebrile general tonic and clonic convulsion and progressed to typical West syndrome consisting of clusters of myoclonic spasms of the extremities, mainly on the left side, accompanied by head and eye deviation to the right side. Electroencephalogram (EEG) presented typical hypsarrhythmia and cranial computerized tomography (CT) and magnetic resonance imaging (MRI) showed massive heterotopic gray matter in the right hemisphere with the same density or intensity as cortical gray matter. Single photon emission computed tomography (SPECT), using N-isopropyl-p-123I-iodoamphetamine (123I-IMP), demonstrated decreased blood flow in the ectopic lesion. Although clinical response to several anti-epileptic drugs was poor, her seizures were well controlled by relatively low dose adrenocorticotropic hormone (ACTH) therapy of 0.015 mg/kg per day followed by a combination of valproic acid and clonazepam. 相似文献

Hirschsprung's disease has been considered to cause intestinal perforation in rare cases. Even if a perforation occurs, the majority of cases are associated with the long-segment or total colonic type. Our case developed the perforation in the neonatal period in spite of being of the recto-sigmoidal type, and it affected the cecum. We do not have a good explanation for this condition. However, the pathological examination of the specimens of the perforated cecum revealed some necrosis (ulceration, subcutaneous hemorrhage, congestion and severe edema) which was considered to be caused by ischemia, secondary to a localized vascular accident in the wall of the distended intestine. 相似文献

SUMMARY: Advanced glycation end products (AGEs) have been found to accumulate in the amyloid deposits, skin and plasma of haemodialysis patients (HD), implicating the possible involvement of AGE-modified protein in pathogenesis in dialysis-related amyloidosis. Pentosidine, an AGE cross-link, is a specific marker for AGEs. Plasma pentosidine levels in HD patients were increased dramatically. In the present study, plasma pentosidine, fructoselysine, advanced oxidation protein products (AOPP) and glutathione peroxidase (GSHPx) levels were measured to elucidate the role of oxidative stress in pentosidine formation in nondiabetic HD patients. Plasma pentosidine did not correlate with fructoselysine; plasma AOPP levels were significantly higher than those in normal subjects (201.45 ± 57.93 vs. 55.91 ± 6.57 μmol/L, P <0.001) and correlated positively with plasma pentosidine in HD patients ( r =0.52, P <0.005); plasma GSHPx levels were significantly lower than those in normal subjects (168.40 ± 65.08 vs. 348.87 ± 86.10 U/I, P <0.001) and correlated negatively with plasma pentosidine ( r =0.54, P <0.001) in HD patients. Decreased GSHPx levels may lead to the accumulation of hydrogen peroxide. These findings implicate the involvement of oxidative stress in the accelerated formation of pentosidine in uraemia and suggest that pentosidine could be considered as an oxidative stress biomarker to estimate the degree of oxidative-stress-mediated protein damage. 相似文献

Abstract— Concentrations of homochlorcyclizine enantiomers in blood, urine, and tissues of the liver, lung, kidney, brain, heart, spleen, intestine and stomach of rats after drug administration were determined by high-performance liquid chromatography on a chiral stationary phase. After intravenous administration (10 mg kg?1), homochlorcyclizine was rapidly distributed in many tissues, with the highest concentration in lung. No differences were found between enantiomers in blood concentrations. After oral administration (50 mg kg?1), the concentrations of the (+)-isomer in nearly all tissues were higher than those of the (–)-isomer. The AUC0-x values of the (+)- and (–)-isomers differed significantly. The absorption of racemic homochlorcyclizine from rat small intestine was not enantioselective. These results suggested that the different concentrations between enantiomers after oral administration were not caused by enantioselective absorption or distribution but rather by preferential first-pass metabolism of the (–)-isomer in the liver. The enantioselectivity of metabolism was also demonstrated by in-vitro experiments. 相似文献
